input: sensors: accel: mxc6655xa: add missing sync events.

Browse source 
If there is no mutex lock between run and active in aidl,
closing the sensor when reporting an event will cause an address exception.

After we added the mutex lock, we found that the reading process
would be blocked probabilistically when waking up from deep sleep,
and activating the sensor at this time would cause a deadlock.
Adding a sync event fixed this issue.
